ARB METHOD STATEMENT Cwmbran
1.0 EXECUTIVE SUMMARY
A survey of the existing trees has been undertaken on and adjacent land to the existing Stagecoach Bus
Depot and the adjacent undeveloped area north of Edlogan Way and between Heol Dewi Sant to the west and
Somerset Road to the west. With Fox Removals abutting the undeveloped land to the north.
The survey has been carried out by David Rice Forestry a suitably qualified and competent Arboriculturist in
accordance with British Standard 5837: 2012 Trees in relation to design, demolition and construction –
Recommendations.
The purpose of the survey and of this report is to identify the impact of the proposed developments which are
the new Stagecoach Bus Depot and a Lidl Store both with associated parking.The survey of the trees
immediately adjacent the site will be undertaken in accordance with the provisions of BS5837: 2012.
2.0 INTRODUCTION
The Tree Survey was undertaken 11 December 2018 by David Rice Forestry after a landscape assessment
was made by Corscadden Associates.
DOCUMENTS
The following documents should be referred to with reference to this statement.
CA 2018-106 Existing Features and Tree Survey
CA 2018-107 Tree Protection Plan and Overlay.
Tree Survey Stagecoach , Cwmbran NP44 1PD 11 Dec 2018
The documents used in preparing the Tree Survey were
The Topographic Surveys and proposed layouts for the proposed Lidl Store and Stagecoach Depot.
3.0 EXISTING SITE
The site slopes from north to south and is to be developed separately into by Stagecoach for the northern
section as a new bus depot and in the southern section by Lidl for a proposed store.
STAGECOACH PROPOSED AREA
This area is the current undeveloped site and part of the original bus depot. Stagecoach Section with
approximately a 1.40m fall north south for a length of 152m. The site varies in width but is generally
approximately 90m wide.
To the north is a green palisade fence abutting Fox removal with an internal boundary strip of colonising scrub
with buddleia dominant.
To the west is a green palisade fence with a narrow strip of existing vegetation of seedling trees, hazel, holly
and some bramble which widens in the lower southern section and is gapped in places. There are two oak
trees T18 and T19 in this strip. A footpath abuts the narrow vegetation strip by the fence and there is a wide
grass verge with trees up to Heol Dewi Sant. Internally on the west side of the site is a strip of scrub vegetation
and debris which is wide in the central section and lower section and a few trees have been felled.
To the east is the green palisade fence with two gate access points alongside the tarmac footpath of
Somerset Road. Internally the northern upper section has rough grass verges on either side of the gates with
seedling trees. The gate is locked and has a line of boulders behind it. The central section has a rough grass
verge by the second gate and south of the gate the verge widens and there are 4No Norway Maples T1-4 with
scrub vegetation and bramble.
The southern boundary is an open boundary with the original bus depot parking area. The proposed bus depot
are is split into three sections. The upper undeveloped site is old concrete bases and is separated from the
central section by a line of felled Cypress trees with the stumps still in place. The central section has a wide
scrub block on the west side and and the Norway Maple block on the east side the remainder of the area is a
hardsurfacing used for parking. The central area is separated from the lower area by a narrow strip of low
scrub. The lower area is all hardsurfacing.

LIDL STORE PROPOSED AREA
This area is currently the existing bus depot building and part of the parking areas. The Lidl Store Section hasa
1.40m fall north south for a length of 117m. The site varies in width but is generally approximately 89m wide.
To the north is open to the Stagecoach Proposed Area and is all a hard surfaced area.
To the west is a green palisade fence with a of existing vegetation of seedling trees, hazel, holly and some
bramble and is gapped in places. There are trees within the wide Heol Dewi Sant verge whose roots spreads
reach the site boundary T14-17 Norway Maples. T6 ad T8 Sycamores whose roots extend into the site
area.The west boundary by the old depot building is a line of felled Cypress species, Ash and Norway Maple
outside the palisade fence.
To the east is the green palisade fence with two gate access points alongside the tarmac footpath of
Somerset Road. The first gate is in the upper section and the palisade fence insets around a derelict building
and its parking area centrally on the east side. The lower section of the east side has the second gate. The
lower east boundary by the old depot building is a group of felled Cypress species and Norway Maple both
inside and outside of the palisade fence.
The southern boundary is an open boundary of grass areas south of the old bus depot building up to Edlogan
Way.
3.1 TREE PROTECTION ORDERS : STAGECOACH AND LIDL AREAS
No TPO trees within the site boundaries.
3.2 TREE REMOVALS
STAGECOACH AREA
No tree removals within Stagecoach Area.
LIDL STORE AREA
No tree removals within Lidl Area
There is an Off-Site tree removal recommended in the tree survey T10 Norway Maple where the
recommendation is to consider the removal of the tree and as much stump as possible to reduce fungal
spread. It is advisable to let the Newport Tree Officer know of the situation as they may wish to fell the tree to
reduce the infection of adjacent healthy trees in what is an important amenity group.
3.3 TREEWORKS
Only trees within the site area or immediately adjacent will be listed below.
STAGECOACH AREA
T1 Norway Maple – Kill Ivy
T2 Norway Maple – Cut out deadwood. Tidy snags
T3 Norway Maple – Kill Ivy. Monitor weeping necrotic spots
T4 Norway Maple – Curt out deadwood. Tidy snags.
T18 Oak – Kill Ivy
T19 Oak – Kill Ivy
Note when clearing the vegetation around the 4No retained Norway Maple retain 3.5 brambles cut back to
150mm above ground level by the fence.
LIDL AREA
T6 Sycamore – Kill Ivy
NOTE All the trees where the ivy is to be killed are to be checked for evidence of bats by an ecologist and
guidance provided by the ecologist on the required procedure and timing to manage the ivy if bat evidence is
found.
3.4 ROOT PROTECTION AREAS OF RETAINED TREES
The Root Protection Area’s (RPA’s) of trees to be retained where possible will be within the protective fence
line kept in place for the length of the construction period.

ARB METHOD STATEMENT Cwmbran
STAGE COACH AREA
Protective fencing is required around T1-4 Norway Maples on the east boundary. Small sections of the roots of
T1 and T4 will be cut in implementing the bus depot proposals. The chassis wash unit is to be located by the
edge of the tree area. Great care is required to ensure that minimal excavations are required beyond this edge
line to minimise damage to tree roots.
The tree area has uneven ground. It is to be cleared of vegetation and debris and can be graded as necessary
beyond the tree root area. The ground can be minimally graded and low points infilled for ease of future
maintenance.
T18 Oak is offsite but the RPA Roots spread significantly into site are to be fenced off.
T19 Oak only a mall area of roots are likely to extend into the site and will be cut back during the parking
space construction. A protective fence to be placed to protect the tree canopy during general construction
works.
LIDL AREA
The Roots of T6 And T8 Sycamore extend into the site area and are to be fenced off. Small section of the
roots of T8 Sycamore will be cut back to facilitate the carpark construction.
4.0 SITE ACTIONS
This (AMS) Arboricultural Method Statement is set out for the implementation of any aspect of the
development that has the potential to result in the loss or damage to a tree. This AMS sets out the work which
will be carried out at Stagecoach Area and Lidl Store Area.
SITE MONITORING
The arboriculturalist will undertake the following site monitoring
STAGE COACH AREA.
Briefing meeting with Principal Contractor and Tree Surgeon – confirm the fence location
Confirm the tree works and trees where tree roots are to be cut.
LIDL AREA
Briefing meeting with Principal Contractor and Tree Surgeon – confirm the fence location
Confirm the tree works and trees where tree roots are to be cut.
BEFORE WORKS COMMENCE ON SITE
Site meeting with Principal Contractor to confirm
Protective fencelines to be erected before building demolition works occur. Fencelines to be checked by
Arboriculturalist and confirm that they are correctly located. The fence can only be altered/or removed
only with Local Planning Authority agreement until construction is complete.
DURING CONSTRUCTION
STAGECOACH AND LIDL AREA
ROOTS TO BE CUT. The excavations into the RPA are to be minimised. All excavations are to be carried
out by hand. The roots extending into the excavation are to neatly hand cut and neatly cut back 50-75mm
from the face of the excavation. The excavation face to be covered with damp hessian until the carpark or
other adjacent construction is undertaken.
STAGECOACH
NO DIG CONSTRUCTION Three Parking spaces on the western side of the site require a ‘No Dig’
solution. The area was previously a scrub area and is therefore a topsoiled area. The area should not be
tarmaced. Considering the general site levels and the likely proposed levels the simplest solution would
be use Gopla grid system with a gravel infill using the Golpla Quick Lay System with Everedge metal
edging to contain the grids. If any excavation is required limit it to 50mm. Refer to the Gopla Appendix
4.1 PROTECTIVE FENCE LINE
The installation of the protective fencing shall be located as shown on Drawing No 2018-107 Tree Protection
Plan and Overlay before the commencement of any works on site, for protection against damage to trees to

ARB METHOD STATEMENT Cwmbran
be in accordance with BS 5837: 2012 – Trees in relation to Construction. The extent of the construction
exclusion zone and line of the protective fence will be marked out on site to ensure all site operatives are
aware of the areas which are to be protected and excavation avoided and compaction minimised in these
areas.
A tree protection barrier shall be erected prior to any site activity starting and the construction exclusion
maintained until the end of the construction period when the soft landscape works are undertaken. The tree
protection shall be in accordance with BS 5837 2012 – a temporary fence of Heras weldmesh fencing with
anchored feet and a scaffold poles driven into the ground to provide a static barrier. Refer to the diagram
extracts from BS 5837: 2012.
Additional precautions to avoid damage to trees will apply to the working site outside the construction
exclusion zone as defined in BS 5837 : 2012. Signage will be attached to the fencing ‘Construction Exclusion
Zone Keep Out’ Particular care will be taken to avoid any damage to tree branches during the operation of
construction machinery and the transportation of tall loads.
Other than works detailed within this method statement or approved in writing by the Local Planning Authority
(LPA) no works (including any vehicular movements, storage or dumping materials, stripping soil) will take
place within the exclusion zones defined by the protective fencing.
Works within the Exclusion Zone are restricted as follows:
No vehicle movements.
No fires to be lit.
No storage of construction materials or spoil
No soil levels to be altered.
No site huts to be placed within the zone unless of ‘jack-leg’ construction.
No excavations or installation of below ground services to take place within the zone unless
agreed as part of the planning permission. Any permitted excavations within this area will
be hand-dig only or using trenchless excavation techniques.
If roots are exposed during excavations, those below 2.5cm diameter can be trimmed back
to the edge of the trench with secateurs. Roots with a diameter greater than 2.5cm should
be covered with hessian to prevent dessication and the trench backfilled as soon as
practicable.
No site notices/ lighting/ signage etc to be attached to trees to be retained
No mixing of cement or discharge of contaminants i.e. fuel within the zone
The ground should be protected from pedestrian movement if required by using boards or
geotextile membranes.
4.2 SERVICE INSTALLATION
STAGECOACH AND LIDL
Proposed incoming services are to be located to away from the RPAs of retained trees.
Refer to NJUG Guidelines for Planning, Installation and Maintenance of Apparatus inn Proximity of Trees
(Volume 4) 2007
CONSTRUCTION ACTIVITY
The storage and preparation of construction materials is prohibited within the construction exclusion zone and
trafficking will be kept to an absolute minimum necessary to construct the development. All tree protection to
remain in place until construction is complete.
4.3 STAGECOACH ‘NO DIG’ SOLUTION
Three Parking spaces on the western side of the side require a ‘No Dig’ solution.
The area was previously a scrub area and is therefore a topsoiled area. The area should not be tarmaced.
As the area is for carparking the finish can be
4.4 NEW TREE PLANTING.
STAGECOACH AND LIDL
New tree planting is to be undertaken on the boundaries to mitigate for the losses and for visual amenity.

forms of vehicular hard-standing.
Designing sub-bases for grass
When designing with Golpa®, consider the inherent
drainage characteristics of the site, as grass will only
thrive on well drained ground. Design of the sub-base
is derived from the loads to be carried and prevailing
ground conditions. Suitable for both ‘Green-Field’
and ‘Brown-Field’ sites, the sub-base will consist
typically of a 200mm thick layer of well compacted
free-draining stone (MoT Type3) followed by a 100mm
layer of Rootzone. Golpla® is then laid and consolidated
with a vibrating plate and loose filled with clean friable
top soil and seeded. It is important not to overfill the
modules or to compact the soil within them.
Designing for stone Designing for successful grass growth
Sub-base for stone retention is subject to load and ground As all major seed houses agree, good grass requires a

Application: Car parking area laid to grass and gravel
Location: Boscastle, Cornwall
Project details: 4000m2 Golpla modules manufactured in
black at client request
Following serious flooding in 2004, part of the
major flood prevention scheme, entailed
construction of a new car park on land in the town
centre owned by the National Trust.
Whilst recognising that visitor car parking in this
busy tourist town would, of necessity, need to be
robust and hard wearing, the Trust were anxious
to use natural materials and quickly establish grass
cover. Geosynthetic’s Golpla® ground reinforcement
system was selected by the main contractor,
Carillion, and approved by the client, their
representatives (Halcrow) and the National Trust as the
ideal combination of robustness, simplicity and speed
of installation, and long term durability and
sustainability.
